CVE-2020-3454 (GCVE-0-2020-3454)

Vulnerability from cvelistv5 – Published: 2020-08-27 15:40 – Updated: 2024-11-13 18:10

Title

Cisco NX-OS Software Call Home Command Injection Vulnerability

Summary

A vulnerability in the Call Home feature of Cisco NX-OS Software could allow an authenticated, remote attacker to inject arbitrary commands that could be executed with root privileges on the underlying operating system (OS). The vulnerability is due to insufficient input validation of specific Call Home configuration parameters when the software is configured for transport method HTTP. An attacker could exploit this vulnerability by modifying parameters within the Call Home configuration on an affected device. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying OS.

Severity

7.2 (High)
